Description

The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit. This OMEGA Speedmaster HB-SIA Co-Axial GMT Chronograph honours the Solar Impulse project and its aim to fly around the globe powered only by energy from the sun. It features a black carbon fibre dial graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with central chronograph and GMT hands. The black bezel, with its tachymetric scale, is mounted on a 44.25 mm titanium case and presented on a titanium bracelet. At the heart of this numbered edition timepiece is the Co-Axial calibre 3603. Etched on the caseback is the patch of the Solar Impulse HB-SIA project.
